定时调用...
您的这段码应该添在什么位置？hwndMain的定义在什么位置？
LPMEMORYSTATUS lpBuffer // memory status structure
);
这是API函数的定义形式，参数lpBuffer下面类型的结构：
typedef struct _MEMORYSTATUS {
DWORD dwLength;
DWORD dwMemoryLoad;
SIZE_T dwTotalPhys;
SIZE_T dwAvailPhys;
SIZE_T dwTotalPageFile;
SIZE_T dwAvailPageFile;
SIZE_T dwTotalVirtual;
SIZE_T dwAvailVirtual;
} MEMORYSTATUS, *LPMEMORYSTATUS; MembersdwLength
Size, in bytes, of the MEMORYSTATUS data structure. You do not need to set this member before calling the GlobalMemoryStatus function; the function sets it.
dwMemoryLoad
Windows NT 3.1 – NT 4.0: The percentage of approximately the last 1000 pages of physical memory that is in use.
Windows 2000: The approximate percentage of total physical memory that is in use. dwTotalPhys
Total size, in bytes, of physical memory.
dwAvailPhys
Size, in bytes, of physical memory available.
dwTotalPageFile
Total possible size, in bytes, of the paging file. Note that this number does not represent the actual physical size of the paging file on disk.
dwAvailPageFile
Size, in bytes, of space available in the paging file. The operating system can enlarge the paging file from time to time. The dwAvailPageFile member shows the difference between the size of current committed memory and the current size of the paging file — it does not show the largest possible size of the paging file.
dwTotalVirtual
Total size, in bytes, of the user mode portion of the virtual address space of the calling process.
dwAvailVirtual
Size, in bytes, of unreserved and uncommitted memory in the user mode portion of the virtual address space of the calling process.

这个贴子为了多收集方法先不揭帖。希望大家集思广益。

以上是strSysInfo的入口參數STDMETHODIMP CMultiThreadDlg::GetSysInfo(long *plResult, CString strSysInfo)
{
CString str;
PDH_STATUS pdhStatus;
HCOUNTER *pCounterHandle; PDH_FMT_COUNTERVALUE fmtValue;
DWORD ctrType;
CHAR szPathBuffer[MAXPATH]={'\0'};
pdhStatus = PdhOpenQuery (NULL, 0, &hQuery);
pCounterHandle=(HCOUNTER *)GlobalAlloc(GPTR,sizeof(HCOUNTER));
strcat(szPathBuffer,strSysInfo);
pdhStatus = PdhAddCounter(hQuery,szPathBuffer,0,pCounterHandle);
pdhStatus = PdhCollectQueryData (hQuery);
pdhStatus = PdhGetFormattedCounterValue (*pCounterHandle,
PDH_FMT_DOUBLE,
&ctrType,
&fmtValue);
*plResult = (UINT)fmtValue.doubleValue;
return S_OK;
}
我用過了，可以的。
